Hi hskswm and welcome to the eForum
Thanks for your post here. I'm sorry to hear that you are having problems with this. I can appreciate how frustrating it must be for you.
I've just checked your coverage in your area and there are currently no problems with the surrounding cell sites that I can see. Can you confirm if you are able to get 3G coverage outside of your home?
If your iPhone is draining its battery quickly its probably advisable to put the phone onto GSM only - Settings>General>Network>Enable 3G>Off
This will prevent your phone from constantly searching for 3G coverage.
You can indeed use a Sure Signal to give you 3G coverage. All you need is a broadband connection
Please let me know if you have any more questions and we'll be more than happy to help you further
Thanks
Wayne
