miui uh?
thanks for the information @tomauswustrow
searching ,over and over again i founded a great deal
one mb860 or best know as motorola atrix.
it is upgradeable to ics,it has 1gb of ram a dual core by nvidia,the tegra 2
hdmi out,usb otg and it has the ability of transform itself on laptop if the owner has a dock.
is the unlocked version
i bought for only 70USD including shipping
i wanted photon q 4g ,i am in brazil but in ebay i can only find locked versions to american carriers,the unlocked version cost an arm and a leg
and at least if i dont like the atrix i can re-sell it for USD200-250 in brazil
in my country taxes are very high and i will get one atrix without taxes so liking or not liking the phone i will have profit

can someone explain the tricks and tips behinde android?
cause as i said i never had a strong contact with android,only five or ten minutes isnt experience enough to judge well the operating system.

will i have all the apps and functionalities that i used to have and play in n900 maemo 5?
