I notice that lately more and more owners of iPhone terminals are asking how they can get rid of the iPad baseband, how they can solve GPS problems, etc. I want to clear up once and for all the iPad baseband upgrade/downgrade issue so you know what to expect in the future. You can install iPad baseband only on iPhone 3G/3GS and the iPad baseband version is 06.15.00. You can check the baseband of your terminal by accessing the section Settings>General>About and the value written next to the name Modem Firmware is actually the value of your baseband.
Well, now that we have found out where an iPad baseband can be installed, what is its version and how can we check the baseband version of our terminal, let's answer the question in the title. You CANNOT get rid of the iPad baseband at the moment and there is a possibility that the iPad baseband will remain permanently in the iPhone terminals. To get rid of this baseband, one of the following 2 things must happen: Apple releases a version of iOS with a baseband higher than 06.15.00 (iOS 5 beta 6 has baseband 05.20.x) or the Dev Team releases a solution baseband downgrade.
Apple will not release a version of iOS with a baseband higher than 06.15.00, so you can take your thoughts from such an idea and the Dev Team does not seem to have a solution for baseband downgrade, so you can take your thoughts from this idea as well. Basically, if you have iPad baseband in your iPhone, you stay with it forever, because there is currently no hope that that baseband can be returned to a lower value. I hope I have answered your question, I hope you will remember it in the future.
