Let's start with the Dell phones first. Engadget talks about leak this and leak that, but it's obvious that Dell simply planted the relevant photos and specification sheets right in Engadget's lap. There's various Android phones in there, as well as a Windows Phone 7 device.
The Windows Phone 7 device is called the Dell Lightening, a beautifully designed portrait slider (a là de Palm Pre) with some impressive specifications: a 1GHz QSD8250 Snapdragon, WVGA 4.1" OLED display, 5MP autofocus camera, 1GB of flash with 512MB RAM plus 8GB of storage on a MicroSD card, GPS, accelerometer, compass, FM radio, and full Flash support with video playback. If this is an indication of the phones Windows Phone 7 is going to run on, than the future of smartphones is looking pretty good. Expect this device to ship in Q4 of this year.
If Windows Phone 7 isn't your thing, Dell also has a few Android smartphones lined up, which look equally impressive. The Dell Thunder is the figurehead model, with almost the same specifications as the Lightening (the camera is 8MP, though) but with probably an even more impressive design. This one will also get Flash, as well as an "integrated web video Hulu app". Q4 of 2010, as well.
Then there's the Dell Flash, which is supposed to be a cheaper but still capable Android phone. Specs are all a little less impressive compared to the Thunder, but still very respectable compared to today's phones. Once again, it's slated for a Q4 2010 release.
Android on the iPhone and Pre Plus overlocking made easy
This seems like a no-brainer: running Google's Android on the iPhone. It has taken a little longer than expected, but PlanetBeing has managed to install, run and dual-boot Android on the iPhone; support for the 3G should be easy, the 3GS is trickier.
Overclocking the Palm Pre (Plus) has been possible for a long time now, but it has always been a touch job. Those days are over - a new tool has been released where you can overlock your Pre (Plus) to 550, 600, 720, and 800MHz with a single tap.
Pretty sweet, but of course, while Palm doesn't prohibit you from doing this (like some other companies would), they do warn that this will break your warranty. At your own peril.
