I have an iPhone 3G and am sick of it dying every now n then. This has started since the update to OS3.1. Sometimes, it just gets super hot and dies due to battery outage. most of teh times though its just a software freeze. click the home key, no response. the only wayout is to press power key + home key for 10 secs. that reboots it. Anybody with the same probs ? shud i contact apple and/or softbank abt this ?
