I have the old pre 3g IPhone, TX and Th-55. Which ones do I prefer for Wifi browsing? The IPhone can get you spoiled for some of the graphics but for reading TX and TH-55 are a better PDA for reading.
Loading full long pages give all small PDAs problems. TH-55 and TX won't load images so that speeds the process of browsing. Wifi on the early IPhone is not sensitive because the antenna on the TX and Th-55 are much more sensitive, thus a wifi source doesn't need to be closeby or strong.
The most miserable wifi device is my PSP. Typing without a keyboard and no google search restricts the amount of surfing possible. For a short while downloads for a Naruto Amine was possible for free and not via a PC. Downloads of MP3 podcasts are easily done by a PSP with an empty memorystick.
