I need a cell phone booster that will work for an iphone. Tmobile has TERRIBLE service where I live. I believe I have more 0 bars about 90% of the time and 1-2 bars when I stick my phone out the window...for about 5 seconds. Sometimes it gets so bad, I can't even send a text because it goes back into "searching" mode. For every 5 minutes I don't have service, I get approximately 15 seconds of service. I've timed it.
What can I do?
