The iPhone 5 will be launched during an Apple keynote speech during the first week of August. This would therefore place the release date of the iPhone 5 in September.
This is simply very strong evidence to suggest the aforementioned. However, this does not mean that it is 100% true. On the other hand, it could very well be true considering Apple are looking for a way to deal with the performance of the Galaxy S3 as soon as they possibly can.
Furthermore, with leaked images of the iPhone 5 surfacing in the last few days it seems more likely that an August launch date is possible. However, no more information in terms of specs, design, availability or price have surfaced but keep your eye out and Laptops.co.uk will ensure you hear about it first.
