I have a 8830 world edition and currently running v4.2.2.176 on Verizon. I have been trying to update my phone, but for the last week, when I try hooking up my 8830 to my Imac or laptop, neither can locate my 8830. I have tried several hard reboots and not my 8830 will only hold half a charge. The error message I get when I hook up is unrecognizable device...Please help...Any ideas. I'm thinkng I need to take it in to see if any software issues may be the issue.
