Is it worth getting the IPhone 4S or IPhone 5?

My blackberry is really annoying me now with me constantly topping it up every week because it runs out of credit. I think my phone just loses credit for no reason and that makes me mad! So, is it worth getting the iPhone 4S or iPhone 5? Or just not get an IPhone? I'm starting to save up.

I have the iPhone 5 and love it, but it is quite expensive, it depends on how quickly you can get the money and how soon you want the phone

The new iPhone 5 is technically superior than 4S but that doesn't mean 4S is bad. Read the following.

iPhone 5 has the following advantages over iPhone 4S:-
Larger screen(4 inches vs 3.5 inches) with 16:9 aspect ratio(better for viewing HD videos)
Better front(Now HD) and rear camera(better low light performance)
Better processor with more RAM, faster Wi-Fi.(relatively more future proof device)
Slimmer design and more use of metal in construction and lighter

iPhone 4S has the following advantages over iPhone 5:-
CHEAPER!
Has all the features that the iPhone 5 has
Old 30pin connector has more accessories available

If you're looking for an iPhone, go with the 5 or wait for the next version as you have that option. The bigger screen really makes a huge difference. More than you would think. Everything is up to 6 times faster from the 4s on the 5, and aesthetics like the screen colors are improved, the rear camera lens is now made of sapphire crystal, and the front facing camera has improved quality. I've dropped it plenty of times without a case on hardwood, and though it sounds like it got damaged pretty bad, I pick it up, wipe off the dust, and it's still in perfect condition. Definitely a nice buy. I like it. I'm thinking about switching to android but not quite yet, just because of how fluid apple's software is, and with iOS 7 coming out, I can't see my self switching over. Get the 5 or the next version!

The 5 is just a bigger 4S. It's just more expensive and more annoying.

5 is obviously best but I think 4S is also really good for the price.

Well as far as you loosing credit I highly doubt that has anything to do with the phone. But comparing phone to phone an iPhone 5 would definitely be better than the BlackBerry.
