Not sure which it is, and the answer will lead me towards either a new, better phone, or just a new battery. I got my Eris a little over a year ago, so it's out of warranty, and it always had the occasional problem where it would either freeze when the screen was off, so I'd have to do a battery pull, or I'd take it out of my pocket to find that it was restarting. It went through a few phases where it did both of those things a handful of times per day, then it stopped for a while, then started, then stopped. Just recently, it's picked up again, and this is about 2 months after I rooted the phone, and until now, it's been great rooted. I've only really noticed this again though since I switched from KaosFroyo to CelebFroyo, but again, I also had these problems BEFORE I rooted too. Any ideas?
