If it costs me, say, 2 cents a minute to call a landline in Europe and, say, 25 cents a minute to call a cell phone in that same city- why isn't there a service (in Europe) that allows me to call a landline which connects my call to a mobile phone (and charges me 5 cents a minute or a monthly charge or whatever) Or, is there?

My (non-existent) ideal device is a Treo -- with wifi, GSM/GPRS, and either EDGE or HSDPA -- on a service plan that includes flat-rate unlimited data, flat-rate international data roaming, and a small amount of voice usage inside the U.S. (say 100 mins/month).

Is there a way to have two cell phone accounts on one phone? To make things more complicated, I'm talking specifically about combining a Nextel account and a Cingular account -- which I believe operate on seperate protocols. Is there hardware that supports this? I'd want to be able to have both accounts active at the same time, and if I were on a call using one, and received a call on the other, the other would get pushed to voicemail.
A very good friend of mine had her cellular telephone stolen the other day, and by the time she noticed this and reported the theft to T-Mobile, the thief had made many hundreds of dollars worth of calls to a foreign nation. After many calls back and forth, T-Mobile says they are doing her a great favor by waiving 25% of the costs but she is responsible for the rest. Is this right? Why would they treat a supposedly valued customer of several years this way? The T-Mobile reps tell her there is no appeal process or ombudsman; does anyone know if this is really true?

I've got batteries on the brain today (slightly-earlier post about aftermarket laptop batteries), but this thread and my growing frustration with my increasingly-relied-upon cell phone brought to mind another question: how much battery life does your cell phone really get? No matter where I am, how much I use it, or even if it's on or off, my Samsung SPH-N400 gets 24-36 hours per charge, at best, compared to the advertised "Talk Time: Up to 2.9 Hours, Stand-by Time: Up to 7 Days."
