Well it appeared that my Lumia 710 died (later was able to get it working again by doing a hard reset), so T-mobile sent me a replacement (refurb) phone. My original would not install the 8773 update; however the replacement came with it. Trouble is the only difference I can see is the internet sharing option. Supposedly I thought we would be able to resize live tiles, however this phone does not give me that option. Holding down a live tile only gives me the standard unpin option. Does the 8773 update provide this functionality?
