Oh i would agree and if i had an iPhone 4 i wouldn't be concerned with upgrading.
However i have a 3gs and although iOS 5 made my 3gs snappier, in all respects its still super slow compared to my fiance's iPhone 4 and obviously the new 4s.
It just bugs me when from time to time my phone locks up on certian things Ex. takes about 20 seconds to open my camera roll, locks up when trying to get to my wifi switch, just switching pages on the homescreen locks up.
Its basically simple things that SHOULD NOT be buggy or slow which are in fact slow thats bugging me. Now this isn't ALL the time, but about 3 to 4 times a day i generally deal with a lockup of a simple task that shouldn't be locking up.
oohh I thought you had a 4..
Well it doesn't hurt to ask. I think it's how people ask and how long they been a customer. So many people feel like they are owed it (not sure if that is the word I am looking for). They feel like they can go into a store and demand it and they will get it. When they don't they come on here and complain about it how evil the company is, but that person is the one who signed a 2 year contract and no one forced them too.
I always felt if you ask nicely, calm, and even make the sales person you're in a good mood that you will get a lot further. Once you raise your voice in any way... you lost.
Also try asking on a Friday, I seem to get better deals with Comcast on Fridays, doesn't hurt with AT&T.
