Cell Phone signal improver

We all know about those bogus ads for that little decal of a circuit, which you put under your cell phone battery, and all you do is waste your money. However, what I am looking for is something which you can REALLY improve your signal, not just some hype. I have a Nokia 3585i Cell phone, on Sprint's network. I have poor signal inside my house, and in a few other towns near me, and when I have a poor signal, my battery enjoys killing itself [like fully charged battery to dead, just in 8 hours of 10% signal]. I could switch my service elsewhere, but that's just too much hassle, and I like Sprint's plan. Now, here is what I want to do, I want a small circuit which I can tie into the antenna somewhere, so it will boost the signal, sufficiant enough so I can use it in area's I couldn't, and not kill my battery. Any suggestions? -justin'89 Bonneville Super Sexy Edition

That your problem you have sprint. After phones companys allowed you to take your number with ya. CNN did a report on it. See which was a beter company. here

Well, the problem is, I am under my mom's plan, which of course means I can't switch, but she has to. I have talked to her about this and she won't go for it, because she runs her business through her cell. In January I am eligable for a $150 off a new phone from sprint. My whole idea was crushed because of budget problems, and the fact I don't have schematics for the phone. If the signal doesn't change with the new phone, I am either going to experiment with different companies, or just go big or go broke, and dig into my old cell phone to try to get a better signal throught that. So basically my quest has ended, but thanks for your reply! -justin'89 Bonneville Super Sexy Edition
