1: Each webtext can be up to 5 messages, or 765 characters. At 160 characters per message, that's 4 x 160 characters and 1 x 125 characters. Why is the 5th message truncated?
2: Are there any plans to allow sending webtexts of 6 or even 7 messages, like was possible on the old O2 system?
3: Can the display be adjusted to show the number of characters remaining in the current message, as well as in the overall webtext? This would be helpful to know if shaving a few characters off what you're writing will result in one less message being required.
4: A linefeed seems to count as 4 characters, when it should only be a single character (0x0A in the GSM spec)
5: Extended characters such as square brackets or the Euro symbol seem to count as 3 characters, when they should only be 2 (0x1B escape character plus the extended code, e.g. 0x1B 0x65 for the Euro symbol).
6: On the old O2 platform, if you clicked Send after your browsing session had expired, the webpage froze but you could still manually copy the contents of the webtext you'd been trying to send. On the new system, clicking Send after your session expires dumps you unceremoniously back at the login page, losing the webtext. Can this be fixed?
7: Do you have any plans to permit saving of Sent webtexts? Three have previously stated that this missing functionality is due to a technical limitation of the new platform. If you'll pardon my bluntness, when do you plan to fix said platform?
Adding two more:
8: You can't schedule a webtext via Safari on iPhone. The date/time picker doesn't appear, even when you request the desktop version of the site.
9: (As called out by other posters) There's no way to view / amend / cancel a scheduled web text.
