[8525, TyTN, MDA Vario II, JasJam General] DeviLduck:
1. This unlocked HTC TyTN originally came with 05/30/06 ROM installed. I tried different HTC, Dopod, Qtek,I-mate, etc. ROMs available on this Forum but the current one (7/22/06 shown in sig) being used is the most stable I found. All were about the same speed wise. All have the same BT audio problems. Some ROMs really choked with certain utility software, e.g., Spbs & SKtools. Some ROMs are loaded down with stuff you'll never use & can't get rid of easily. This ROM works the best here with demanding chess software & online chess programs, as well as various utilities which are known to cause problems. The real improved TyTN ROM we need isn't released yet!

2. Serial # HT628xxxxxxx. No screen alignment problems.

3. 2 GB SanDisk MicroSD card, formatted as fat32, correct memory detected on device. No data losses so far. I have made backups (Spb) to card & restored with no problem, USING SAME ROM ONLY. All syncs (MS4.2) made to WinXPsp2 computer...works normally.

4. Cingular network settings used = same as Cingular 8125. Found that the TyTN Phone setting\Band settings WORKED BEST when BOTH set to AUTO. When specific settings, i.e., GSM or WCDMA, GSM(1900+850)+UMTS(1900+850), were used, the speeds were much less or erratic for some reason I don't understand. In fact, UMTS connects infrequently & Edge drops way down. This finding may only apply to San Francisco Area. The tests performed all used the DSLReports Test Server-S.F. & 2Wire.com server. A soft reset was done between each test or change of parameters.

5. Also, I found that the Cingular (8125) setup for MEdia Net (which also uses proxy settings) works the best & attains the highest speeds overall. Other settings, especially those needed for audio & video streaming (where proxy is not used), were not as good. Tests included TyTN Cingular settings from various websites, e.g., BengalBoy, etc..I'm still working on finding the optimal settings for non-proxy use. However, I will say, I've been able to play online chess & listen to streaming audio, simultaneously, something not possible with any other ppc or mobile device used. So, even the non-proxy connection through Cingular with TyTN works well.

6. The device Network setting indicates "UMTS Cingular" when connected to UMTS. For G (Edge & less), the Network setting will indicate only "Cingular."

7. Top pda screen indicator U or G. Of course, G appears for Edge or less bandwidth. Speeds generally average about 175-260 kBit/sec Edge or 600-1200 kBit/sec UMTS. The higher speeds are happening more frequently around the San Francisco Bay Area, as Cingular improves the network. Areas where I used to get only Edge speeds are now coming in as UMTS.

8. It's possible Cingular's use of HSDPA software is beginning to bump up the average UMTS speeds, in S.F. area.

9. The TyTN gets much better phone signal than my 8125 & about the same as the excellent 2125. Old Nokia still best in this department. The phone audio quality, both in & out, is MUCH better than Cingular 8125 or I-mate Jamin.

10. I have noticed more Dropped calls with the TyTN, compared to the 8125, 2125, I-mate Jamin & an old Nokia. Maybe that's due to Cingular Network changes related to UMTS, who knows, but others have reported this as well.

11. The TyTN sliding keyboard is heads & shoulders above the 8125! Totally solid mechanism. Thank heavens. It's easiest to use of any pda keyboard experienced.

12. Besides the useful registry BT tweaks one needs for the TYTN, I did find the reg tweaks to pipe the History, Cookies, & Temp Internet Files to MicroSD card, an excellent improvement! With the better TyTN Internet speeds, this tweak means more than before.

13. Using Clip-on Bluetooth Stereo Headset, DKSH-06, spec v1.2.(Shenzhen Trykey,Hongkong) & Motorola H700 BT earpiece. Both excellent with TyTN.
