Today I make a backup and restore my iPhone 4S cuz its unlocked by att.
When I turn on my iPhone with straight talk sim I have the icon 4G not 3G I don't know what happen.
I turn of and turn on back it's the same icon 4G
Somebody has the same on the 4S?
I'm guessing you updated the software at the same time and in newer software the HSPA+ network (which the iPhone 4s is capable of) shows up at 4G... technically it's still 3G but they want you to think the iPhone is faster than 3G, considering there's all this 4G marketing out there.
I buy broken/used iPhones (4 & 4S) on any carrier! PM me info about your phone and your asking price and I'll get back to you!
HSPA+ is 4G along with WiMax and LTE. None of them were 4G until the International Telecommunications Union-Radio changed the specifications on December 6, 2010.

It's really only 4G because no one could make up their minds as to what actually was 4G and carriers started calling their services 4G before a standard was even set.
HSPA+ technically is still 3G technology, just faster. LTE should have been 4G but because there were already people stating they had 4G, that's why you see 4GLTE everywhere.
We know the truth whether they advertise it one way or another.
Following your reasoning, there is no 4G anywhere. No technology qualified as 4G before ITU-R changed the definition. You should read some of the background material before trying to speak ex cathedra.
Following a detailed evaluation against stringent technical and operational criteria, ITU has determined that “LTE-Advanced” and “WirelessMAN-Advanced” should be accorded the official designation of IMT-Advanced. As the most advanced technologies currently defined for global wireless mobile broadband communications, IMT-Advanced is considered as “4G”, although it is recognized that this term, while undefined, may also be applied to the forerunners of these technologies, LTE and WiMax, and to other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed. The detailed specifications of the IMT-Advanced technologies will be provided in a new ITU-R Recommendation expected in early 2012.
