iPhone Tethering and MMS Hacks Surface
The first hack, brought to our attention by Engadget, activates tethering by modifying a user's carrier settings file. The hack utilizes specific carrier settings files from a wide range of carriers around the globe, opening up the method to a large number of users.
Essentially, you use your iPhone to browse to a site that you've never heard of (help.benm.at), download a file that promises to reconfigure your local carrier profile, and then switch on tethering as you would had you tithed a monthly tethering fee to your carrier. We've confirmed that it works on T-Mobile NL and on O2 UK. There's obvious risk here so be careful and backup your iPhone first before giving this a shot. And don't go nuts either -- remember, your unlimited data plan likely contains a "fair use" clause and you can bet that carriers won't be happy to see their bandwidth diminish without compensation.Carrier settings files for all carriers (not just AT&T) are also available through iPhone-notes.de. Some users have reported that the hack disables MMS and visual voicemail on their carriers, so users should be aware of the possible trade-off.
Gizmodo offers up a second hack that can enable both tethering and MMS.
Our first method comes from Giz reader Aaron Krill, who has posted a comprehensive guide -- a sort of super-powered update to our old 3.0 tethering hack -- to enabling both tethering and MMS specifically on AT&T. It's not the simplest procedure, but it's approachable, and doesn't require jailbreaking like before. The gist:
- Enable IPCC updates on iTunes 8.2
- Update IPCC files
- Spoof AT&T's website into thinking you have an other phone
You should proceed with caution with any of these potential changes as they are unofficial and unsupported.
