I just have a link in my PDA to provide a page with a select group of airports I've determined. And the source? ADDS, of course! It's valid for aviation use and there is no disclaimer like Flightaware has. I bring up the page and get both METARs and TAFs for north Georgia and down through central Georgia.

Here is the text but ignore the link. The way this system interprets use of brackets, it cuts off at the first left bracket. You'll have to copy the entire line as text into the browser and modify it to meet your needs. It should be usuable on any web-enabled phone with the only limitation being the amount of text allowed.
For some odd reason, ADDS won't let me have simply KGVL for my first entry. It cuts off that airport entirely. So, I listed it a second time and it comes up normal. To alter it, all you need to do is pick your own group of airports to enter between the brackets. Should you desire the translated English version, change the "raw" to "translated" and you'll get just that.
