says for advanced users only. So if you decide to try this and something goes wrong you have been warned.
MuscleNerd has announced a few CommCenter hacks which enable iPhone 2G MMS and iPhone 3G/3GS tethering.
iPhone 2G owners can enable native MMS with a patch by Wh1terat and geniusan. This procedure will modify your CommCenter and as such is quite dangerous. Only advanced users should attempt the steps found here.
iPhone 3G/3GS owners can enable tethering in iPhone 3.1.2 by performing a different CommCenter patch. It's just a 2-byte patch; however, its also recommended for advanced users only. You can learn more about this patch here.
We are still considering whether to post tutorials for these hacks. Eventually they will be made a part of normal PwnageTool flow. Its also likely that someone will post a tool or package to perform these procedures.
