The Bestselling Signal Boosters for the iPhone 4 & 4S:
About the iPhone 4 and 4S
The iPhone 4 was a completely redesigned evolution to the iPhone 3G. It featured a stainless steel frame which also acted as the phone's antenna, as well as improvements to the camera, processor and other components of the iPhone. While there were some problems initially with the iPhone 4 antenna, those were fixed solved by Apple and future versions of the phone were defect free. The iPhone 4S was an improvement upon the iPhone 4, and included a much better processor, improved camera, and featured facetime and Siri on the phone.
What is a Signal Booster?
A cell phone signal booster is a system that receives a good signal in one area, amplifies it to be even better, and then broadcasts it to an area which does not have good signal. Cell phone signal boosters are used frequently in situations where materials in the construction of a house, office or vehicle prevent the cell signal from effectively reaching the phone, and provides the ability to circumvent these problem materials and provide a quality signal to the receiver.
Does the iPhone 4 or 4S Support 4G?
While the iPhone 5 does support 4G for increased data speeds, unfortunately the iPhone 4 and 4S do not support this technology. Thus, if you're looking to increase cell phone signal for your iPhone 4 or 4S, then you'll be looking to boost the 3G signal, with no need to boost 4G.
Support for 3G
The iPhone 4 and 4S phones both fully support 3G voice and data standard, so if you're having trouble with cell phone reception with either version of the iPhone, then you'll want to get a signal booster which boosts the 3G signal.
