hey guys! i recently moved into a new a appartment and my fiace and i both have evos and we get week signals. funny thing is that its strong to get texts calls and very weak 3g. the phone rings but when i answer the person on the other side does not hear. my question to you guys is, is there any kind of a repeater or signal booster i could install that could strengthen my signal? i thought of the airave but dont really wanna pay extra for unless theres a way to "unlock" it and do it for free.
