Two Iphone Or One Iphone And One Ipod Touch?

Rumour is back to square one as now Apple is said to release two different Iphones, yes two instead of one which now most source are expecting. But two? whats the difference? One will be the one which all source are saying, big screen, thinner, lighter, faster with A5 chip, that is the first one. The second one is said to be a low end Iphone for competing in the low end market with Android which is selling very fast which conquers the market with a huge volume.

But again from another source, the low end isn't exactly an Iphone but and Ipod touch but what makes it different from the other Ipod touch and makes people think that its an Iphone is the spport for 3G connectivity. Now Ipod touch finally getting a 3G connectivity like the Ipad which have two variation WiFi and WiFi+3G and looks like Ipod touch is joining in the party. Now this seems more reliable and as Apple said there will be only one Iphone, so could the Ipod touch is the one making all the thought os a second Iphone in the making? Look like it from here
