tech behind AT&T's spin on the home-based femtocell repeater since January, and in February a little iPhone update revealed that we were getting closer to prime time. Finally, news of limited trials and then... silence. AT&T has apparently been keeping its head down, diligently testing its MicroCell service, with 200 lucky subscribers having Cisco boxes beam full bars to the darkest corners of their living rooms for months, testing that has been successful enough for AT&T's Gordon Mansfield to say that it's still "on track for a full national launch." That's the good news. The bad news is that he continued by saying it'll release sometime "by the end of 2009." So, you might be in for up to six more months of dangling your iPhone out the window to get your voicemail, but hold tough -- you can make it.
