I got my iphone 4s about a month and a half ago, and it was sweet, service worked 24/7 there'd be the odd no service but it would only last a few seconds. Now with the new update, my iphone gets hot really quickly (the battery) and I've noticed that I'm receiving 'No Service' constantly. And it lasts up to minutes and it seems to be a constant thing now, nothing to do with my network coverage because it was fine before, it worked with a breeze then right after the update it started doing this. It's a real pain because I'm quite the frequent caller/texter via cellphone and now I can't text that much without receiving the 'Message Send Failer' constantly. And I'm afraid calls will also drop because of this. Anyone have any suggestions or feedback? or any similar experiences? because this is really starting to bug me.
