yeap i did. i put it down to installing a lot of apps though. so i shut it down for a few minutes and then turned it back on again. worked much better. also i found having the sync going on in the background (which the market app irritatingly has to have on) will also slow things down.

 

When I first got mine, was slow and thats because some installs in marketplace got stuck from automatic updating.

So check all that.

Sync..what have you got linked to it (twitter, facebook, htc sense, facebook sense contacts, etc)

 

I had this problem on and off for a few days when I first got my DHD.

I found a way to fix my issue, I installed a cache clearing app that keeps an eye on the application cache for me. Since installing this I've never had an issue and my handset runs as fast as it did the first time I turned it on.

I've also installed Titanium Backup Pro today and removed Amazon MP3 Store and Soundhound. These are 2 of the 'bloatware' included apps that come on the DHD that you can't normally remove. Getting rid of stuff you don't use will free up resources - but you need to be careful that they aren't tied in to the system to avoid problems.

 

Been good. Sim free from p4u. No such problems.
But I'm really tempted to root this little beaut. Mmmmm....

 

I've done it. It was worth it for the Cache clearing, full backup and removal of the Soundhound and Amazon MP3 store apps to be honest.

 

I had the same problem only got my phone last night. There is an option under Settings/Applications/Development/USB debugging. Checked the option box and it's running smooth as
