Last week, the Gevey Team announced their SIM Interposer for the iPhone 4. This SIM Interposer would provide the long awaited iPhone 4 unlock or Baseband 2.10.04 and 3.10.01.
Although there was some speculation as to whether this SIM Interposer was legit or not, today a reader over at Redmond Pie has provided evidence showing an iPhone 4 with 2.10.04 baseband running on T-Mobile USA's network using the Gevey SIM Interposer.
