I am upgrading from an LG Optimus V (Virgin Mobile). This phone was great for me due to the developer community, however the time has come to use a modern (hardware & software) phone.
Same here, besides a couple of short term substitutes from the time I deactivated the OV until the Nexus 4 arrived. It is amazing what the dev community did with the OV; at the end I was running Jelly Bean on it. It had a number of bugs, but it worked. Night & day difference though between the OV & the Nexus 4!
