Gigapets versions?

[Tama_Tarots]

Hi guys!
So, I know that for original Tamagotchis there are lot of different version and wave shells; but what about Gigapets? Unfortunately I'm really new on this type of v-pet, but I'd like to know what version are the two models in the photos in particular (I already know that are both Compu-Kitty, my question is more tecnichal).
On the Tamenangerie site (apologize in case this is considered spam) there is a mention about a nano version but I really don't understand of what photo the site talk about, so if someone can clarify what is the first shell version, what is the nano version and what version are mine, well I'll really appreciate your help and I'll think this can be useful for other people.
P.S. Don't worry for the strange logos in the photo, they aren't fake; those simply are the italian version of gigapets, that were renamed "Bit-Bit" under Gig's company (personally, a very poor choise).

Nobody have news about this topic? I'd really interested to know Gigapets versions differences!

Hey, I just came across this thread and I mention some differences between Nano programming and regular GigaPets programming in my current log here. (You can scroll down to the post in that thread that says "Giga Pets Info Deep Dive.") The log I'm doing right now is for a Bitty Kitty with regular GigaPets programming. Next I'll be doing a log for a Bitty Kitty and a CyberKitty with the Nano programming.
