I was under the impression that 4.6.x.x was going to be the Bold's OS version while 4.7.x.x was going to be for the Storm. I don't understand what an OS 4.7.x.x would offer for the Bold that it does not already have.
Just for the record, I hate seeing a post about a speculated new OS with the speculated OS version as the title. Imagine how many disappointed people are going to run across this over the next few days/weeks--especially if it is indeed only speculation.
