As the posts I make are all coming from my mobile (cell) phone I thought I should share some information about it.
My phone is the Sony Ericsson P910i on an Orange 200 minute contract. I have an allowance of 25Mb of data traffic on GRPS-WAP. Email headers are around 1 - 2k so I check 2 email accounts with no problem.
The internet browser is OK but I have downloaded the free Opera browser, which handles Javascript pages better.
The wordprocessor is fine - once you realise it saves.pages in an html format and you just need Save As on the computer you send material to for converting it to a full doc. (I have attached a draft example from a doc I wrote on this phone).
The phone works well, keeping connection even when the 5 bars drop to none on the reception counter. I can also record and play video.
Internally the phone has 64Mb available storage and takes Sony Memory Stick Duo cards for plenty of extra storage (it comes with a 32Mb card).
The phone works well with bluetooth and infrared. Though I email much of my work from the phone, the extra options have saved situations such as at meetings where it is found that a laptop does not have the expected floppy drive.
This phone runs on the Symbian platform and there are loads of programmes you can get; www.handango.com is a good start.
One excellent piece of software, that rounds up a lot of the phones features, is Handy Day 2005. I can get an instant view of weather forecasts, RSS feeds eg BBC News (but I can add any others I want eg blogs pages) and it summarises things such as Calender, reminders, etc.
I had the P800 for 2 years and decided to get a new phone (+number) earlier this year. I checked www.freedom-mobiles.com and www.smalltalk.com and found the P910i for around £100 (around $184) for the phone when choosing a 200 minute Orange contract. Not being sure of how I went about cancelling my Orange contract I called Orange Services and chose the Thinking of Leaving Orange automated option. I said that I was looking at getting the P910i but would be taking out a new contract as the price was so much better than upgrading and keeping my number. The guy on the other end asked where I was looking at getting the phone from and how much. After a few moments, (I reckon he was looking online to check), he said Orange would match it and I could therefore keep the number while saving a huge amount. If you're on Orange it might be worth a try.
I use a Sony Ericsson HBH-300 bluetooth headpiece that doubles up, via bluetooth dongle, as the headphone for my Skype phone service, (internet based phone service - free software, free between users and very cheap to landlines especially abroad).The headpiece has a long boom and seems to avoid excess background noise.
Other accessories include bluetooth or infrared keyboards that pack up really small.
If you've been looking at the SE910i I hope this helps.
