Tatto 4G Flash / Huawei E357... is really a 4G?

Based on the internet I learned that:
- HSDPA (3.5G) = up to 14mb dl
- HSPA+ (4G) = up to 21mb dl

If my knowledge is right E357/4G Flash is actually 3.5G unlike the E353/Smart Rocket which is 4G! Which I think make sense because of e357/4G Flash's cheaper price.

So that's it... Globe's fail marketing on 4G naming -- at least for me. Also I don't think unlocking will make e357 to access HSPA+/4G.
