Sprint slashes iPhone 4S price, waives activation fee as anticipation for new iPhone grows
Does that mean it’s a good time to get the iPhone 4S on Sprint? Probably, but if that September 12th date for the next iPhone launch comes true, in just a month the iPhone 4S will cost $99.99 on contract at all carriers, and you’d have a brand new iPhone that will make your 4S feel a bit dated. The iPhone 4S is still a great phone, though, it has one of the best cameras you'd ever find and is compact, and passed the test of time. If you’re all about the savings and you need a phone now, this offer is definitely something to consider.
Sprint stands out among other carriers with its unlimited data plans, but many users complain that unlimited data comes with extremely slow speeds.On the other hand, again, there is the rumored sixth-generation iPhone that is widely expected to feature a larger screen, blazing-fast 4G LTE connectivity and tons of other features. Patience, patience...
