Should I Get a iPhone 5 or Wait for the 5S?

I Have a iPhone 3GS and My Upgrade is Up in Jan 2013 and T-Mobile is Positive to Get the iPhone 5 in 2013 (1st Quarter)! But I Don't Know if I Should Get the 5 or Wait for the 5S!

That's easy. The iPhone 5 was released long before it was ready. You definitely should wait for the the 5S.

Entirely up to you.

5 then
5S 9 months from now

I normally see more of an improvement from a regular model to an S model than I do from an S model to the next generation's model.

For example, the 4S was MUCH better than the 4, but the 5 was only a little better than the 4S.

Thus, I would wait for the iPhone 5S. Think about all of the bragging rights (and all of the cool features) you will have that your friends won't! If you really like Apple technology, just get a 5th generation iPod touch now. But in terms of phones, I'd wait for the 5S because that phone is bound to be sick.

Get the iPhone 5. The 5s will just get a faster processor and a few more little upgrades. There was not a lot if difference between the 4 and 4S. The 5 is a great phone and the phone I currently own. I upgraded to the 5 because I had the 4.It is better to be on the number release cycle rather than the S release cycle.
