Okay G1 owners, so here's the end-all answer to your data roaming quandaries. For those not caught up, there has been quite the hubbub going around about the G1's inability to not suck down data whilst traveling aboard. Allegedly, the handset would continue to digest pricey bits and bytes overseas even after users had selected that data roaming be disabled. Now, T-Mobile has issued an official response (posted in full after the break) to clear things up, and the gist of it is this: for users with a bone stock G1, the "Off" selection in data roaming should work fine, but third-party applications can essentially override this command and wreak havoc on one's phone bill. From the horse's mouth: "Some third-party applications available for download on Android Market require access to the internet and have the ability to turn on data roaming when in use. Customers are informed whether an application will use this feature prior to downloading, but should also be aware when traveling outside the country."

Official T-Mobile statement:

T-Mobile is committed to delivering the best experience in wireless to our customers. If a T-Mobile customer would like to use their T-Mobile G1 while outside the country, they should contact Customer Care before they leave to ask that the WorldClass feature be added to their service at no additional charge. If they choose, customers can also disable data roaming on the G1. This can be done by going through the following steps: Home Screen > Menu > Settings > Wireless Controls > Mobile Networks > Data Roaming.

Some third party applications available for download on Android Market require access to the internet and have the ability to turn on data roaming when in use. Customers are informed whether an application will use this feature prior to downloading, but should also be aware when traveling outside the country.
