There was an issue with he GTalk application not working if you switched. Also the current thought is if you want to go to GMail, you will have to reset your phone and build the account back up again from scratch.

 

I switched mine over 2 days after getting my phone, so it was ok to do a factory reset.

 

One thing to check is, once you have changed, that you can sign into Gtalk and more importantly, you can download from the Market!

 

had no probs since the change

 

yeah was annoying

 

Had a thought on this.

I'm sure when I changed the Mrs' google password, the phone asked her to confirm her user details again including googlemail username.

Wondering if this would work to change the default to gmail?

The only other way requires root access:

EDIT: here's how to change your primary google account and keep everything happy without wiping your phone!

Credit to someone else... not me!

If you want to change your primary gmail account for Gmail, its much easier.
Don not hard reset means set to factory defaults , by erasing all data and application , instead go to
1. Settings -> Applications ->Manage Applications ->
Here you have to "Clear Data" from
1. Gmail
2. Gmail Storage
3. Gppgle Apps
4. Google talk and Talk services
5. and IM. (Would be rare to have this showing unless you are using Google IM)
clearing data is much simple just click on aplication and clear data.
"
the Dev also warns that Google Storage will want to keep filling up so do that one last before exiting Manage Applications section.
Then, of course, you must regularly restart your phone, when it comes back, you will need to enter your new chose gmail, then follow the instructions. You also should do a *228, 2 for OTA, but may not be needed. What may be needed is having to do a *228 , 9 (as previously instrcted at any Verizon Store when you bought the phone in the first place).
This method of changing the an Android devices primary gmail account actually works. So let's all stop the goddamn FUD that we can't change the primary email AND LET CUSTOMERS KNOW and/or right a batch file with a shortcut in Manage Applications so that we can just stop all this bickering. Now this next part is probably why Google, Android Market, Verizon employees, Motorola CS employees are all saying "it can't be done", is probably due to the next relatively complex procedure:
The apps PURCHASED need only be re-registered, but in order to NOT Download and pay for them again, you will have to remove your CC from the old gmail/Google Checkout and use it in Google Checkout with the NEW gmail you have chosen for your new Droid primary - sure beats re-DLing and installing all those apps. Unfortunately the CC has to be the SAME CC you used on the old gmail account otherwise you ARE stuck with re-purchasing the apps from the Market using the NEW gmail you have chosen along with the different CC/Google Checkout.

 

Hi. I've just followed these instructions, but it's for my Hero, not Desire.

It's worked in so far as the old Googlemail account has cleared, but now I don't seem to be able to sign in with my new Gmail account. The data returned is:

"This could be a temporary problem or your SIM card may not be provisioned for data services. If it continues, call Customer Care".

Any ideas?

 

Check your date and time are right and disable auto time update.

 

Nope, looks like I'm going to do a factory reset :-(

I've backed everything up. The only things I can't find are small images that I have set for my contacts. They're not on the SIM, and they're nowhere to be found on the SDCard. Anyone know where they are, or am I resigned to losing them?

 

Guys, when you switch to gmail instead of Googlemail you always have the option in the accounts settings in Gmail to switch back (full Gmail, not on your phone).

I realised that it wasn't letting me use the new Gmail details without doing a factory reset, so I just went back to Gmail > Accounts > Change back to GoogleMail - rebooted the phone and it was all working again.

Until Google fix this properly - I don't think it is worth messing about with. It doesn't really matter if people send email to you at gmail or googlemail - they will both work and get to you. It is far more important for your phone to work, so until Google sort it, leave it as Googlemail.com. Unless you have just got your phone and don't mind a factory reset.

 

Does anyone know why I can't change back to googlemail.com?

I've looked on the web under Settings - Accounts and Imports in the "send mail as" section, but I just don't get the option...

 

I would advise Android phone users NOT to switch from Googlemail.com to Gmail.com. I did and had the problem reported by hundreds (possibly thousands) of users - that is, I could no longer download from Android Market and Google Talk (which I didn't use on its own, but on which the market depends) failed to authenticate.

If the phone gave you a way to amend the authentication details this wouldn't be a problem. As it is, Google needs to fix it - and doesn't seem in any hurry to do so. Deleting cached and saved data didn't work for me, even after rebooting the phone. The only way I was able to get round the problem was by switching my account back to Googlemail.com.

 

Is is still relevant? Just wondered if Google had addressed (no pun intended) the issue or not.

 

Easy way, although time consuming - reset your phone and start again with the @gmail.com version of your address...job done, but it does mean you have to set everything up again

 

Ok thanks, think i'll leave it then. Lived with it for this long so can manage

 

Only real way to sort it. Ended up doing this myself. MyBackup Pro made things much easier though.

 

Well... it didn't work for me... I only have the gmail app installed, and clearing its data and re-starting the Desire achieved nothing. It's still using that old account I'm using for anti-spam... If I had known from the start why I had to select a gmail account when setting up the phone, I wouldn't have chosen that particular account, but there was no info about that... This is starting to tick me off... Such a simple thing, change the default account, and it can't be done without resetting the whole phone. What were they thinking...?

 

Has this problem ever been fixed - I'd quite like to change my googlemail to gmail, but have never doen it due to the reported issuses - been a year now?

 

Not fixed properly. On the Google forums there was a solution that involved changing and leaving it 24hrs!! Seemed to work but left behind traces of the old googlemail account on the phone. Get the trial for MyBackup and just factory reset the phone. Most things restore nicely and it'll probably only take around 30 minutes. May even clear your phone out and speed it up a bit.

 

A lot of people have had issues with the market, this is defo one thing you should check!!
