Flash 10.1 is set to bring a step change in the way that the Web can be interacted with on mobile phones, but the latest statements from Adobe indicate that Windows Mobile 6.5 users will be left out in the cold - only Windows Phone 7 owners will be able to use Flash 10.1.

Adobe's Antonio Flores said: "We have made the tough decision to defer support for that platform until WinMo7. This is due to the fact that WinMo6.5 does not support some of the critical APIs that we need". While that won't win the company many fans among the Windows Mobile community, it pales into comparison compared to what's rumoured to be in store for Android users.

It's being reported that certain Android handsets - those without an ARM v7 Cortex chipset - won't be able to download Flash 10.1 either. That's the vast majority of Android handsets out there, with exception of the Nexus One, Motorola Droid and upcoming HTC Legend and Desire. Adobe wouldn't be drawn on the truth in this statement, however, saying: "All Android devices that meet our minimum s/w and h/w requirements will be supported.  Unfortunately, I cannot say a lot more publicly about our port to the Android platform at this time".

Flash 10.1 will be showing up in the middle of 2010 on most platforms with the exception of the iPhone. Apple has protested that Flash drains the battery too much, so won't be supporting it, but Adobe has fought back with a video claiming that is not the case.
