Seeing increasingly large #'s of comments like that in the App Store from 4 and 4S owners.
4 and 4S can decently run the latest OS version. The 3G and 3GS were really bad in this respect, but all devices supported now are pretty decent. There can be performance problems, but apart from real time games I don't think it's a widespread issue (users of these devices are already used to general slowness)
Do you really consider the iPhone 4/4S obsolete? To me this sounds like an unrealistic idea of real-world upgrade schedules. The iPhone 4S was released in October 2011. I would hope that a device of cost O($1000) would last more than 2.5 years.
Well Apple still sell the 4S. So, it's understandable.
huh, I have a 4S as my primary device and it runs 7 & eveyr app I have very, very well
