Resurrecting a very old threat here, but I contacted effect.2010 (the eBay seller mentioned a few times on her) and they still are not doing the upgrade cables with the mic. I was lucky enough to get the TF10's quite cheap, although I do need a mic for work calls and for Facetime/Skype calls with the family.
The stock UE vi cable here in the UK is £30 delivered, and I thought if I was spending that much to upgrade the Triple.Fi 10's I bought last week then I might as well look for a proper upgrade. Something with a more rebust connector. I use with a Blackberry, Cowon S9 and and iPad (usuallly in landscape), so I think a right angled connector such as the Neutrik's would be desireable.
So far, the only really impressive looking option is the Beat Audio cable here, but that's $200 which is really more than I was willing to spend.
