May I know can HTC Legend officially upgrade to OS 2.2 Froyo?
Other than Legend, how about Wildfire, Aria, Desire?
And wat mean by "root"? is it if upgrade to froyo we need to root our phone?

For extra inquiry;
i) may I know what mean of "AT&T"?

AT&T is a US carrier, something like Maxis, Digi and Celcom

Desire already been upgrade to froyo... Wildfire still unknown... as for the other both i dont know...

Root mean giving full access to your phone system... On other word you can change anything you want and flash custom froyo rom...

thanks you but sorry again, because i planning to buy a 2nd hand phone, then they stated tat it is rooted to froyo...
but i still not very clear wit root as ur explaination...
to root a hp,is it we nd do ourselves?
is it good to root a phone?
is it we have to root our hp in order to upgrade to froyo?
root is something like format? like we format our PC?

thx again n sorry for my lack of knowledge

If u new to phone, juz use it as it is... root will void ur warranty n may brick ur phone..

In linux world root is a superuser. When ur 'rooted' thats mean ur phone already have the superuser permission. So can flash new rom aka os into ur phone without restriction. Depends on ur phone model, like htc desire already have official froyo update hence u dont need to root ur phone to install froyo. Other than that, u have to root to install custom froyo rom or u have to wait until official release.

Most of android user r technical ppl, we always want to mod our os, install with the latest kernel, overclock our phone processor etc... thats why we have to root our phone

If u follow the guide how to root and flash custom rom it should be no problem. We flash our rom and kernel and radio to get improvement on the performance compare to stock rom.

so complicated, because I am a newbie for andriod phone, now still looking for a HTC andriod phone,plan to get a 2nd hand legend...much to learn n play,haha

Thats y i said if he is new, juz use it.. me myself root my phone n i encourage to root if they know what they r doing....

About the rooted phone, we can still send it back for warranty, right? Just need to flash back to original ROM. Now I understand, but still can someone briefly teach us what you mean by "flash" and "flash custom ROM" (in this case what is a custom ROM), I'm new as well just bought a HTC Wildfire myself. Thanks guys....
