No idea. Ive had mine about 2 months as well, and last night I started having issues. I was running Liberty2.0 at the time, and it was as if some one else had takin over my phone. I could leave it sitting on the counter and watch as it went thru contacts, opened and closed webpages, answered and hung up my phone when the wife called haha.
I figured Verizon would give me hell about having a root, mod and themed phone, so I broke out the d2BootStrapper and restored R2 to his annoying little glory in anticipation of a VZW store visit.
Funny thing, now it works fine. No issues what so ever. Im starting to wonder if these things dont get jumbled up after a while and need to be cleared. I do see many people posting about re flashing and such way more often than I wouldve thought need be. Let me know if you find anything out tho, I just assumed it was Liberty giving me issues.
