I was in tesco looking at some of the samsung android phones and I noticed the original Samsung Galaxy Ace (Cooper), but I also noticed TWO newer Ace+ models. One was a 7500 series and one was 8180. They looked identical, except for the front-facing camera was slightly different. Can anyone confirm this? What are the differences between the models? Can send screenshots of the tesco description if necessary.

There are just a ton of individual models old, new, 2 SIM, et al., then variants within those for different networks, Ace, Ace Plus (+), Ace 2, Ace Duos, ad nauseum.

An I8180 may be a Bada phone?

Take a look at the Samsung Thailand website. Here's the link that shows 30 of their current/newer models, to include the Ace 2 and Ace Plus.

The site shows the full specifications for each phone, athough it won't show any differences like whether it's a 900Mhz 3G for AIS or a 850Mhz for DTAC/True....the specs usually just reflect 900Mhz (guess they assume most customers will be AIS customers). Google Translate is your friend at this web site, but Translate does switch the pages to the English versus just a poor translation.
