do you suggest buying an iphone?

If you need i and if you have the budget for it why not? I'm using it and i have not had any problem with it so far. I can practically do almost everything with it - call, send sms, email, surf, listen to music, watch videos, take pictures and videos etc. etc.

If you live in the US, yes. I noticed that the iPhone would be more affordable if it came with a plan instead of buying it at full price. The cellular networks in the US have great deals for the iPhone, which makes it a good buy. I come from the Philippines and the plans here that come with the iPhone are highly impractical. So it really depends where you're from. If the deals in your country are good enough, go ahead! :D
