signal problem

[ghscion]

ok here is my problem i have a jailbroken iphone 4 on 4.0.1 running the pdf exploit to make my phone think i am on 4.0.2 as of about 2 days ago my signal at my house which used to work perfectly has been screwing up like crazy it will show that i have good signal strength then it will either go down to one or no bars very rapidly and when i go to send a text it will show good signal strength then it will take a million years to send text and finally right before it sends the signal dies and it tells me the message failed anybody had this problem before or know what the problem would be i hate to have to jailbreak my phone again would be a pain but no signal is no good either

Do you have signal problems elsewhere? It may be a carrier problem, not a problem with your phone.
