Quick question, (apology if this is a repeat) I have googled around doing my research before posting this but get extremely conflicting and over-thought postings and guides from sites across the internet, and I figure I might as well just get the information from here and get the information right. I have a standard iPhone 3GS 16GB, non jailbroke, apple firmware. I want to enable the Tethering option but have two concerns: Does enabling just the tether, not MMS, break Visual Voicemail? Have there been reported cases of ATT going after even the smallest tethering usage cases? Assuming the answer to 1 is no and 2 as well, then what is the simplest way to enable just the tether option? Thank you in advance for your time and responses. Cheers.
