I tried about 10 ROMs available in the "CDMA TP2 Upgrades" Section, including custom 6.1, 6.5, 6.5.3, Sense 2.1, Sense 2.5 etc.
I found that only ROMs that TTS can work without any scripts or modifications are EngeryROM and MalROM. Both have Opera Mobile 10 as default browser. So I suspect that the TTS thing must have something to do with Opera 9.5. Of course on stock Sprint ROM, TTS has no problem, where Opera is 9.5 as well (16983).
I don't think Sense is the cause because on Malrom/EnergyROM, the sense is still enabled when I run iGO. But some people get lucky with disabling the Sense, so I guess maybe something related to Sense Internet Tab? Or any settings in Sense that related to Browser etc.?
I tried different registry hacks and so far still have no clue what are the factors that make TTS works on Sprint Stock, MalROM and Energy while not on other ROMS I tried. (With Sense/Touchflo 3D Enabled of course, and it seems Tmail.exe etc. are still there when I run MalROM/EnergyROM).
