I have another thread about stuttery music on the go and one of the suggestions was a factory reset. So I did it. All my contacts are google ones, so they returned to the phone almost immediately, setting up my other email was easy too. However, I have lost all my bookmarks and all the apps that were on my SD card. I wasn't expecting that, I thought the reset only affected the phone, so it's a bit annoying to have to start Angry Birds again but all the others can be re-downloaded and I haven't really lost anything else important. But it got me thinking. Now it's been reset, I'm not going to put back everything that was there before. I'm going to leave the phone in as "clean" a state as I can and see how I get on. I normally turn off Mobile Data to save battery, but I'm going to leave it on and see how it goes. I've got 135mb free on the phone! My photo's and music are intact but I've not had a chance to try the music yet to see if it plays ok. I would almost recommend resetting as it makes you look at the phone in a new light. Do you need all those apps, etc. You could end up with a slicker running phone. I am not going to reinstall 3G watchdog as I never got anywhere near 50% of my 1Gb usage, nor am I going to put back on all the little apps that seemed like a good idea at the time but I never use. I'll see how Peeps works out too rather than put on Twitter (I only use it to read tweets, I rarely post) So all in all I feel I have a fresh "new" phone running smoothly without any unecessary stuff on it. I just need to check the music later on, fingers crossed that will be fine, if it isn't then I guess I'll have to try a faster class of SD card.
