| − | This is the baseband processor used in the [[N82ap|iPhone 3G]], [[N88ap|iPhone 3GS]] and [[K48ap|iPad]] (3G version). It is upgraded with [[BBUpdaterExtreme]]. It is also known as the PMB8878 and is also used on the LG KM900 ARENA. There is a [http://arenoid.com team] working on how to port Android on LG ARENA. |
