How to fix searching or no service problem in my iPhone 3GS?

I'm super desperate to fix this problem! I'm using an iPhone 3GS running on iOS 5.1.1.BB is 6.15. I jailbreaked it using Pwnage tool 5.1.1. I tried to fix the problem by downloading the "ultrasn0w fix 5.1.1" then ultrasn0w itself. Please, could someone please help me \( T^T )/? And thank you in advance. I'm using a mac BTW. Just incase you ask what my desktop is.

Here we go.

  • Sprint Iphone 4 goes from 5 bars to No service and Searching? I called sprint and they tried everything on their end and told me to reset the network settings, even resetting the entire phone, and nothing helped. I read somewhere that the antenna is touchy on these phones and wearing a case may help? I would like to hear any fixes and if anyone else has had these issues. It worked completely fine the first day I had it and then it just started losing service for no reason.
  • Searching for a free Wi-Fi service or, a low-cost Wi-Fi service for myself? Have recently lost everything and must be able to search the web to find help. I do have phone service, no Wi-Fi. Have iphone and apple laptop. Any replies/answers are much appreciated… Thank you.
  • Problem with iPhone Carrier/Phone Searching? A few days ago my phone was working fine the next morning my phone signal said searching… In the top left corner I have no service what so ever I didn't mess with the SIM card. I didn't touch any settings I've contacted Apple and my carrier! I have an Apple IPhone 5c. My bill is paid I don't know the problem I've had this phone over a year now! It's factory unlocked. Is it a possibility my phone factory anyway? I need answers please.
  • No service and searching? My iphone has recently started saying "no service" and "searching", and I need a fix. Preferably I can fix on my own, without needing to go to Apple. Any suggestion helps.
