I just got a new 8310 and I have no idea why but it keeps restarting. The only aftermarket software I have on it is Jivetalk and Facebook. My software version is 4.2.2.170. Has anyone been experiencing this with their 8310?

Also, I don't know if my phone shipped with the right battery. I think my last 8310 came with a battery with rounded edges. This one came with one with sharp edges. The battery says C-S2 on it.
