I've never had an iphone before, simply because I could not afford them. I'm scoring/doing audio for games on the ios now, so need one. My parents have kindly helped out to make it a quasi-xmas gift. I see that the ip4 is 'approaching the end' of it's cycle, and people say a new one will be out in June. I'm not so much bothered about this - seeing as it is hard, without unlimited funds, to keep on top of the latest and greatest. What I'm really asking is, how long before the ip4 becomes "obsolete"? I'm targeting this at folk who have had the older iphones and perhaps are still using them? I asked my mum to order it for me (it is cheaper in Singapore where she lives) and it's been three weeks since so I can't return it. I assume I could sell it in a few months and get a good price (have protectors and a case standing by for as soon as it comes out the box), but the question remains whether that is necessary- even if one comes out in July, will it be a change like from the 3 to 4? Or Minor updates? Will I be able to upgrade to the latest OS? Excuse the speculatory nature, I'm new to the iphone and its workings. Thanks in advance.
