Are there any BlackBerry Tour 9630 owners on Sprint that want to update your device, officially? Not so fast, but you were supposed to have been able to update OTA today to OS 220.127.116.113!
According to this post in the Sprint Community forums by a Sprint admin, Tour 9630 users should have been able to download OS 18.104.22.1683 either over the air (OTA) or download the file to install via desktop manager. However, there seems to be a delay for some reason.
Keep checking the Upgrade option on your Tour 9630 or keep checking back on the software download page. Hopefully we will see this release soon.
