I currently have a Nokia E5 smartphone. Nothing fancy, but it does the job. However, I've been wanting an iPhone for a long time, but the price has been holding me back. The iPhone 4(S) is too expensive for me, but what about the 3Gs ? It's still available to buy so is it still worth it ? I wouldn't mind having an older model, but how does it do with iOS5 ? I've heard mixed feedback : some people say it runs just fine, others say it's dog slow. So who's right ?
