[HTC EVO 3D] kittykat858:
during some testing i have been doing on the 3d - i have had an active data connection and voice connection at the same time.

our chipset: Qualcomm Snapdragon MSM8660 RISC Multi-core microprocessor with embedded DSP

2x Qualcomm Scorpion Harvard Superscalar processor core, 266MHz LPDDR2 memory interface, Embedded DSP (GSM, GPRS, EDGE, UMTS/WCDMA, HSDPA 7.2Mbps, HSUPA 5.76Mbps, HSPA+ 28Mbps/11Mbps, MBMS, CDMA2000 1xRTT, CDMA2000 1xEV-DO, CDMA2000 1xEV-DO Rev. 1, CDMA2000 1xEV-DO Rev. B baseband), Embedded Seventh-generation gpsOne GPS module, gpsOneXTRA Assistance, Adreno 220 GPU

the catch: it was on HSPA+.

What was happening: look up our cpu/radio on qualcomm's site, and you will see it is a cdma, evdo a, evdo b, umts, gsm, hspa, and hspa+ radio. - if u see TrevE's notes on his download mode thread, you can see he connected directly to the radio, and it is a GOBI2000 radio, a global universal radio.

REF: page 18 --> http://www.qualcomm.com/documents/files/what-is-next-for-cdma-presentation.pdf

problem: these is no firmware or software on a stock 3d cdma phone for gsm. nor is there a sim slot.

using some firmware from the gsm phone, and some parts of the gsm rom and kernel - i was able to activate the gsm radio (gsm includes umts, hspa, hspa+)

since i had no sim card, the only phone call i was able to make was to 611 (and good old AT&T answered). the only web page i was able to see (no matter what address i entered) was a while page w/ an AT&T logo that said 'unauthorized device'

TrevE has some info on the partition structure of this phone in his download mode thread. there are some [EMPTY] partitions on the cdma phone that are used on the GSM phone.

i think once TrevE gets download mode done, we can use a 'esim' (or softsim) of some sort to use AT&Ts 14.4mbps hspa+ network

i did pull the 'unauthorized device page' will on the phone w/ 611.

the PCB used in the EU/ASIA phone is the same as the US phone (per HTC's service manual dated 6/2011). the EU/ASIA is short the wimax chip. under the wimax chip, are solder points for a sim card.

since they dont use wimax, but use a sim - and we use wimax w/ no sim - this makes sense. its also cheaper for HTC to have 1 PCB for multiple phones.
