According to a report from folks at TiPb, AT&T customers who have jailbroken their iPhone and using the tethering option unofficially have received a reminder message from AT&T this morning, informing them that they’re planning to update their plan to a tethering plan ($45/mo, incl. 4GB). Back in March, AT&T had sent customers using unofficial tethering options a message stating that “records show that you use [tethering] but are not subscribed to our tethering plan“. To recap, AT&T had started offering the official tethering plans for $20 per month in June 2010, almost a year after the feature was introduced in iPhone  firmware 3.0 by Apple. Due to the delay, developers had released jailbreak apps that enabled tethering for a one-time fee, which are very popular. MyWi tethering app also allows users to convert their iPhone into a wireless router just like the personal hotspot feature introduced in iOS 4.3. It is also one of the causes that leads users to jailbreak their iPhones. AT&T sent several MyWi users a notice last month to cut down on the unofficial use of the tethering. Here are some excerpts from the letter sent to one of the users: [..] Our records show that you use this capability, but are not subscribed to our tethering plan. [..] If we don’t hear from you, we’ll plan to automatically enroll you into DataPro 4GB after March 27, 2011. The new plan – whether you sign up on your own or we automatically enroll you – will replace your current smartphone data plan, including if you are on an unlimited data plan. If you discontinue tethering, no changes to your current plan will be required. The text message that was sent by AT&T today reads as follows: AT&T Free Msg: We’ve noticed you’re continuing to enjoy the tethering feature with your smartphone service. Remember, you need a tethering plan ($45/mo, incl. 4GB) to use this feature, so we’re planning to update your line with the required plan soon. Visit att.com/dataplans or call 888-860-6789.
