The Iambic Forum is alive with reports of Agendus NOT working with the T5, then working "somewhat" if the Agendus app is UNINSTALLED, then the update placed on there, and then Agendus REINSTALLED.
The DIA problem is big too . . . no landscape for some people, who are being warned NOT TO load the typical "DIA 2x apps" we're familiar with due to the T5 having its OWN.
There are crashes of other types, but you'd have to look at the "Bug Report" portion of the forum; I can't remember all the nuances.
MOST IMPORTANT: People are claiming that Agendus is now "verrrryyy sllooooooow," to quote one chap - and Iambic's response to him was that due to the memory changes, the T5 just ISN'T AS QUICK AS THE T3 and therefore Agendus is slower and "oh well!" (that's not a quote). Apparently going from Agendus to AgendusMail is AWFUL.
Iambic are working on it . . . but considering the last "upgrade versions" and how long it took before 8.06 finally fixed everything, I wouldn't hold your breath. Apparently V9.0 is "around the corner;" I've already emailed James to ask if there'll be a charge for me - I just purchased the upgrade to 8.06!! Frankly, unless it address MANY T3 issues, and not just T5 ones, I'd give it a pass . . . haven't had a glitch with 8.06 and I've "got it where I want it." Wonder if they'll break the "1MB" mark on the T5 / v9.0 version?
You have to at least give them credit for trying . . . I wouldn't bother, frankly, if I were a developer. OS5.4 will need so many software fixes IMHO that it might even bankrupt some firms who may find it very expensive to hire the programmers to fix the PalmOne "debacle" they call the T5.
Not that I'm biased, or anything. I'm just glad my stuff works . . . and I tried to warn you good people despite a couple of others on here AND MYSELF being "chided" for being "negative." Well here you go! The results are coming in fast -- Remember . . . be POSITIVE!! So now you have a T5 with "fixed landscape," which doesn't work all the time . . . you can finally synch your calendar . . . alert the media on that one . . . now do you wait 6-8 months for "most" of your apps to work? Just to be in the SAME PLACE YOU WERE with a T3? Am I nuts or is that a ridiculous waste of time and money? What on Earth is the appeal over and above a T3 considering these headaches? It's beyond me.
I've YET TO SEE one review HERE from someone trying out a large number of 3rd party apps, but someone did post a listing on the Iambic forum (same thread) listing about a dozen apps of theirs that WILL NOT WORK -- and it's scary, boys and girls. They're all what would commonly be thought of as "standard but necessary" applications.
