I'm looking for an Iphone Clone, it must have these features below. I've done a bit of searching but can't seem to find the one I'm looking for. I have the Ipod Touch and I really like it but it would be easier to replace it and my phone with an Iphone clone.

Thanks

Features I'm looking for:
Atleast 8GB of space (16GB would work better for me but I couldn't find one, expandable is fine)
WiFi
Can use the same apps as Ipod Touch/Iphone

Has Mail app that can save multiple accounts (gmail/yahoo) like Ipod Touch and Iphone
Works with T-Mobile Sim (dual is fine)
Flash Memory like the Ipod Touch/Iphone (not a hdd, since I run a lot)
