How to get Internet Tethering and MMS support with your iPhone 3G firmware 3.0 and Movistar
Tuesday, May 5th, 2009If you're lucky and you have access to iPhone Dev Center (registered as a developer) you may have installed the latest firmware version, and you may notice that the MMS support and Internet Tethering is not enabled by default, this is because it must be activated by your carrier (in my case Movistar)
First, you have to download this file: Telefonica_es.ipcc
Now, open iTunes and using the Upgrade button with Shift+click (PC) or Option+click (Mac) select this ipcc file.
That's all! it will take only a few seconds.
