OK, first off, I have been searching for a fix for this for some time now and haven't found anything that works so far. I tried to to my best to search before opening a new post so either I didn't search right or its really not out there.
Here's my issue:
I have an iPhone 3G FW 3.1.2 unlocked using ultrasn0w. I have been using this phone for several months and had no issues until recently. My home button went bad so I separated the glass and replaced it. After replacing the home button, my signal strength went down to almost nothing and would only work well when I was close to a tower. Now I can't get a signal at all. Doesnt matter 3G or EDGE, no service. Here's what I have done so far:
Restored multiple times
Re-unlocked and jailbroke multiple times
Tried using blackra1n instead of ultrasn0w
Tried restoring in restore mode and DFU mode
Cleaned main board and all connectors
Reseated mainboard and all connectors multiple times
Repositioned little gold "tooth" near the bottom of the phone
Reset network settings
Reset all settings
Replaced my SIM card
toggled airplane mode on and off
Cried like a little girl
Prayed that it would just start working again
Nothing worked. I am assuming that something happened when I replaced the home button. I am very mechanically inclined and was extremely careful when I did the repair. It would be a huge coincidence if my phone pooped out the day after I repaired it. Everything else on the phone works perfectly besides the phone itself.
Can anyone shed some light on this? Did I miss something? Where exactly is the connection from the main board to the antenna and could replacing the cradle/antenna assembly possibly fix this or would I be wasting my money?
Thanks in advance

check in the lower right hand corner and there are small contacts on the mainboard that i have been told have something to do with reception. i had a board once that had a small crack there and it would get signal then drop it

I didn't see anything noticeably wrong. I tried adding solder to the pad that connects with the spring pin on the antenna thinking I wasn't getting good contact but no luck. I can't figure out what is wrong and it's driving me crazy. I found sone pics online that show where the different sections are on the logic board but I have no way of telling if something is wrong with a specific component aside from visually inspecting it. Has anyone solved this problem by replacing the antenna/dock assembly?

The antenna is connected to the bottom side of the dock connector assembly. Check to see if you damaged it or any of its connections...
