I have dropped very few calls with my 8700c Cingular (Bharti OS), which is a good thing, however, on three recent occasions where I have dropped a call, it causes the BB to go through a reboot which takes approximately 30 -45 seconds to resolve itself. Has anyone else experienced this?

Yes I do on occasion. Maybe 3-4 times over 6 months.

That is wierd so do I, I thought it was just my phone
