booster/repeater to improve coverage?
I just moved into an apartment in the middle of a major city, but I have very spotty coverage and lots of dropped calls. I am thinking about spending around $150 on a cell phone repeater/booster and was wondering if anyone has had success with them on the iPhone on ATT.
Or if anyone has had success with any other method of boosting coverage in weak areas. I've tried a power cycle but with no success. I also read that re-inserting the SIM and doing a full restore may help.
