It wouldn't be a huge shock if the Admire 4G were 3.5". The Admire is 3.5" after all.
Do we have any information on the Admire 4G and L1? The only thing I can find on them is a list earlier this year that turned out to be rather accurate. But then they don't appear on the roadmap leak.
Doesn't help that searching "Admire 4G" is a bit useless...
