They actually got started here. They migrated later to the current domain.Wow.. thanks for the info.... always interesting how forums get started and grow. I started a smartphone forum that got pretty large back in the Pocket PC and Palm days (thus the origin of my avatar). It all started as an FAQ for one device that another forum moderator asked for a volunteer to build. I built it as a forum and it took off. I ended up buying up and merging with several of the competing forums to gain "device share". Bottom line is when the iPhone came along it pretty much trounced things and my monthly traffic went from about a million uniques a month to a fraction of that over a couple of years time. I ended up selling it off while it still had some traffic and value. Today its kind of a tumbleweed wasteland. The dude that took it over got the brainstorm to change the domain name for it and it killed all the deep links to the site that had taken years to establish.
I found out about them some time in late 2012/early 2013 while looking for info on LTE for Sprint. Many of the members are active elsewhere (some of them also have accounts here). But my beliefs about Sprint would have me canned very quickly over there - so I never joined.
It's a great site for information. Not so great if you have an opinion of Sprint/Sprint's actions that is different than that of the moderators/admins. Although they do maintain one or two people to "prove" their objectivity and that they don't ban anyone for having a different opinion (which is BS). At one point members were watching a thread of mine on a completely separate site (sprintusers.com) and rocks were being thrown back and forth. A few MR users I know here have been banned there.
As to your former site, I used to own an HTC Touch Pro so the chances are very good I probably got some info from your site way back in 2009-2012.
