I'm just wondering. I have a 7100g from Telstra which is running v4.0 of the handheld OS. I want to sync it using Bluetooth, but this requires v4.1 of the handheld OS. I have noticed that you can download a Tmobile version of v4.1, but I'm wondering if this will screw up my phone if I install it. When I go to the Telstra downloads on the BlackBerry site, the latest version available is v4.0 still.
Anyone have experience with this kind of thing??
Cheers,
Tim.

No it will not. I used Bharti, Hong Kong CSL, and Cable and Wireless OS's and they all worked.

Just make sure to delete the vendor.xml file after you install the OS to your PC, but before you install it to you BlackBerry.
