I think it might have something to do with an app. Had my phone since it came out and had to power many many times because it would laggg here and there. I read somewhere that someone had there phone for like 2 weeks without powering it off, thats BS...running all those damn apps, that shit does lagg....
I had a problem with my phone the other night where I downloaded an app, I dont remember which one because I tried like 3 and I uninstalled because they were lame, my phone started acting up and it was pissing me off. I couldn't receive phone calls, goes straight to Voicemail, MY SMS wouldn't show up in the notification bar and all of a sudden my HOME key stopped functioning...u don't realize how important that key is until it stops working, believe me....TMOBILE was no help, haha.....freaking hour with them trying to get transferred to PDA dept. who was a dumbass at night. I told her I couldn't receive phone calls cuz I was calling from another phone becuz I know she had to run diagnostics on my G1. She kept leaving me voicemails talking about I should answer the next call because it's going to be her. Didn't I freaking tell her I couldn't receive calls, why is she leaving voicemails? hahahahaha........All i had to freaking do was reset my phone and delete everything, it's back to normal.....dumbasses......
