Got an iPhone on T-Mobile? Don't update to iOS 4.3
Until recently, customers on T-Mobile's Web 'n' Walk Plus and Max services had been able to use their iPhone for tethering at no extra cost; both tariffs allowed customers to share the handset's data connection with laptops and other tech. But with the iPhone's firmware update to iOS 4.3, that's changed. The update has replaced the tethering feature with the widely publicised Personal Hotspot.
Personal Hotspots should offer exactly the same functionality as tethering, and it does - but it's now at a price. A change to the APN settings seemingly means the service provider can see when the handset is being used for tethering. Consequently, T-Mobile are now £2 per day for 250Mb, or £7 per week for 500Mb for the service.
If you're using an iPhone on T-Mobile's Web 'n' Walk and rely on it for tethering, you might be best sitting pretty with the 4.2.1 iOS firmware update or earlier. Meanwhile, since customers are being forced into paying an additional amount for the same service they agreed when they contracted with T-Mobile, we're not sure if there isn't a breach of contract. As far as we can recall, the terms of the Web 'n' Walk tariff aren't SIM or handset dependent.
We'll have a look into it. In the meantime, if you have any correspondence with T-Mobile on this matter, let us know at [email protected]
