3G Revelation!

So I had to post my thoughts on 2 things that has been a big debate for a while now; The “fact” that 3G needs 2 frequencies to operate correctly and the “fact” that European 2100mhz is different that US 2100mhz. I know that challenging this idea is going to get me a lot of emails about how wrong I am but hear me out.. 1. 3G needs 2 frequencies to operate correctly The majority

The new HTC Hero was finally announced (so you G1 users trying to load the leaked Hero ROM onto your G1’s can finally see what it would run like with the beefed up specs the Hero brings to the table). Unlike the Magic, the Hero actually seems to bring something new to the table (besides just losing the keyboard like the Magic did over the G1). It has a nice chunk more RAM (288mb instead

How To: Save Apps to Your SD Card on the G1 (OBSOLETE)

Please refer to the newer Rooting/Loading Custom ROM methods on our site: Unroot (G1) OR Unroot(MyTouch), then Root, then Load a Custom ROM, Apps2SD/Hero etc. So the G1 (or Android, not sure who to blame really), has an inherent flaw.

T-Mobile’s 3G vs EDGE

We do a quick test of whether an unlocked phone (that can only run T-Mobile’s EDGE) can keep up with T-Mobile 3G on the G1. Guess what? It can… RESULTS: Opera 9.5 on EDGE is only a few seconds slower than the 3G on the G1. SkyFire on EDGE is about the same as 3G on the G1. NIICCEE! Then we test SkyFire browser vs Opera 9.5 on a windows Mobile Device to illustrate how

T-Mobile myTouch 3G Caught on Camera

T-Mobile’s second Google Android device has been seen in the wild (with T-Mobile branding and all). So we think this little guy is just around the corner. Question is… does anyone care?

Adobe Announces Flash for Everyone! One of these days…

“Does this phone support Flash?” “Can I goto YouTube without using some YouTube program?” “Does the internet look like it does on my computer?” For most phones the answer to this questions is a resounding “No”. And the reasoning behind the No is the fact that most phones just don’t support Flash. YouTube runs on Flash, most embeded videos, banners, and a lot of games  also run on Flash so without Flash support in the
