TELUS seems to be prepping to roll out the big Windows Phone 7.5 “Mango” upgrade. A support page for the LG Optimus 7 reveals the 500 new features that this upgrade will bring is coming sometime in September, but no specific date. They do note that “If your OS version is 7.10.7720.68, you don’t need to update”… so for those who have the Optimus 7 keep your device handy over the next 10 days. The other Windows Phone devices that TELUS has is the HTC 7 Surround, unfortunately nothing listed for Mango there.
