Ignoring the fact that the picture is a mockup anyway (no carrier and yet it has gprs), it is quite likely that the software is 3.8 since it has a stricter release date than 4.0 does and it couldn't be held up by any possible problems with the whole 4.0 system.
Realisitcally, 3.8 on both 7100 and 7290 will be fairly close to 4.0 given their release dates, while removing any dependancy on things like a 4.0 bes.
