Unfortunately, pre-paid carriers only select low-end phones because they want to sell a lot of them, and higher-end phones are too expensive (remember: no contract, no phone subsidy) to sell in high numbers.
Currently, the Optimus is the best Android phone available on any of the pre-paid carriers. And compared to the other current offerings, it is miles ahead of them. But it is definitely a mid-line phone at best, which is reflected in its low price (around $150-$200).
The good news is that, like everything in the mobile phone world, things change quickly. The Optimus has been a huge success for all of the carriers, proving that there is a great demand for *quality* Android phones even among the "low-end" (according to the wireless companies, who prefer the more lucrative post-paid customers) buyers who use pre-paid phones.
Rumors have Motorola releasing a large-screen, Droid-like Android phone on Virgin Mobile (arguably the best carrier for pre-paid smartphones currently) shortly, and it is inevitable that the other carriers are scurrying to find newer, better phones for their services too. And of course, prices continue to come down, and "base" features improving.
I'm sure in the next few months, you'll see new phones coming available that are much closer to the "superphones" of this past year. But don't expect the latest superphones to ever be available on the pre-paid carriers, because superphone buyers aren't their target market.
i had the virgin mobilel optimus v for a month and liked it but it wasnt as good as an iphone so i returned it. now i will have to wait till august to get another iphone so i think i'll just buy a prepaid android instead. should i get another optimus, a hawai ascend, or the galaxy? its going to be with boost mobile, virgin mobil, or metro pcs
