Google may've let Froyo out of the bag, but until the networks and manufacturers release it that won't mean anything to those ready to kick Android 2.1 to the curb. Sprint and Motorola's (rough/unconfirmed) plans are detailed below.
Sprint's announcement about the roll-out of Android 2.2 is vague, saying only that it'll be seen on their Android phones soon, with the HTC EVO 4G confirmed for the spiffy update - no rooting necessary. The following (unsurprising) confirmation from Sprint -
"As work on finalising the software is underway, Sprint expects to launch Android 2.2 in the near future. It will also be available as an upgrade on the recently launched HTC EVO 4G. With the Android 2.2 upgrade, customers can expect improvements to include the following benefits among others: updates to user interface, improved EAS Support, improved Browser Performance including Flash 10x Support, voice dialing over bluetooth and application storage on external memory."
While Motorola hasn't officially commented on when their Androids - the DEXT, Droid and Droid X - will receive Froyo, a leaked memo from Motorola suggests that the Droid X will get the update in "late August", whereas the Droid will receive it in late July.
We already know T-Mobile is planning on sending Froyo out to myTouch 3G owners, and I'm awaiting a confirmation from HTC today, but if any other networks or manufacturers would like to get in touch with their plans for Android 2.2, please do drop me a line. [Droid Forums via CNET]
